Recent progress in molecular engineering of genetically encoded probes whose
spectral properties are controlled with light, such as photoactivatable,
photoswitchable and reversibly switchable fluorescent proteins, has brought the
new possibilities to bioimaging and super-resolution microscopy. The development
of modern photoconvertible proteins is linked to the studies of light-induced
chromophore transformations. Here, we summarize the current view on the
chromophore chemistry in the photocontrollable fluorescent proteins. We describe
both the fundamental principles and the specific molecular mechanisms underlying
the irreversible and reversible chromophore photoconversions. We discuss
advancements in super-resolution microscopy that became possible due to the
engineering of new protein phenotypes and understanding of their chromophore
transformations.
